"The plan was signed in the early hours of this morning. This day is defined as Day D, i..e. we have two weeks to remove heavy weapons starting from today," Basurin said.

It was also announced that Donetsk militias are ready to continue the prisoner swap with Kiev.

"The next swap will take place already very soon. The exact date cannot be called yet, it is being negotiated. No one is going to draw it out," DNR negotiator Denis Pushilin told Interfax.

The next swap could be held as early as next week, he said.

"We will be swapping all for all, but doing so in one go is technically impossible because of the required clearance procedures and so on. So we, too, will be swapping (them) in groups," Pushilin said.
